Keeping farm pigs cool in the summer is critical to prevent heat stress, which pigs are very prone to because they don’t sweat effectively. Here are the best ways to keep pigs cool in hot weather:
- Provide Plenty of Fresh, Cool Water
- Ensure constant access to clean, cool water.
- Consider adding extra water stations so pigs don’t have to compete.
- Use shaded or insulated water containers to keep water from getting too hot.
- Offer Shade
- Natural shade: Trees or tall brush.
- Man-made shade: Shade cloths, lean-tos, or tarps over pens.
- Avoid metal-roofed shelters without ventilation, as they can become heat traps.
- Misting or Sprinkling
- Use misters or sprinklers during the hottest part of the day.
- Pigs cool off best by evaporation, so fine mist works well.
- Avoid soaking the ground too much if pigs are housed on dirt—it can become muddy and unsanitary quickly.
- Create a Wallow (Mud Pit)
- Pigs love mud! It cools them and protects their skin from sunburn and bugs.
- Choose a spot with good drainage to avoid stagnant water or parasites.
- Offer Cooling Treats
- Frozen fruits (like watermelon) or vegetables make good cool snacks.
- Feed during cooler parts of the day (early morning or evening).
- Ventilate Housing
- Use fans in enclosed barns or shelters to circulate air.
- Make sure barns have open sides or windows for cross-ventilation.
Watch for these signs of heat stress:
- Heavy panting
- Lethargy
- Red or blotchy skin
- Slobbering
- Reduced appetite
If you see these signs, act fast: cool your pig with water, get it into the shade, and contact a vet for further care instructions.
